[Freeswitch-users] Problem receiving calls from E1 to TE122p

[Javier Galaz Jeria]

Hi,

I'm using FS git, on Ubuntu 11.04, with Digium TE122p card (from now on srv1), 
and FS git, on Ubuntu Server 11.04 with Sangoma A101 card (from now on srv2), 
both currently configured by vendor's scripts.

When I make a call from srv1 to srv2, everything goes well, I can hear both ways 
no problem, however when I try it the other way around (srv2->srv1) the 
softphone registered to srv2 gets "User Not Available", hardphone registered to 
srv1 gets INVITE and just after that CANCEL. The FS log: [1]

Looking at the logs I can see that after the RINGING goes to EARLY and tries to 
play ringback tone, but it can't write and it can't read from channel because 
it's not opened. So it hangs up. [lines 520-528]

I've searched the wiki, asked on IRC, but can't solve my problem, anyone who has 
configured TE122p could give some pointers?

This are my config files:

How can I fix this? Any help would be greatly appreciated. If you need more info 
just tell me.
